Examining the Shared and Unique Features of Self-Concept Content and Structure in Borderline Personality Disorder and Depression

A systematic review and meta-analysis of 'Systems for Social Processes' in borderline personality and substance use disorders

Deficits in social processing (SP) have been proposed to underpin interpersonal dysfunction in both Borderline Personality Disorder (BPD) and Substance Use Disorders (SUD). This study aimed to explore potential transdiagnostic cognitive and behavioral phenotypes of these disorders utilizing the NIMH Research Domain Criteria 'Systems for Social Processes'. A systematic review and meta-analysis of the published research was conducted on 134 studies identified through our database searches. Four meta-analyses were conducted, which revealed significant overlapping deficits in the ability to identify facial emotions and infer the mental states of others in both BPD and SUD. Further, people with BPD displayed a higher ostracism effect following perceived social exclusion. Systematically reviewed studies also revealed significant dysfunction amongst individuals with BPD and SUD across both self and other SP constructs, which were broadly similar in magnitude. Taken together, these results support the proposition that SP dysfunction may be considered a core transdiagnostic phenotype of BPD and SUD.

Evaluating Augmented Depression Therapy (ADepT): study protocol for a pilot randomised controlled trial

BACKGROUND

While existing psychological treatments for depression are effective for many, a significant proportion of depressed individuals do not respond to current approaches and few remain well over the long-term. Anhedonia (a loss of interest or pleasure) is a core symptom of depression which predicts a poor prognosis but has been neglected by existing treatments. Augmented Depression Therapy (ADepT) has been co-designed with service users to better target anhedonia alongside other features of depression. This mixed methods pilot trial aims to establish proof of concept for ADepT and to examine the feasibility and acceptability of a future definitive trial evaluating the clinical and cost-effectiveness of ADepT, compared to an evidence-based mainstream therapy (Cognitive Behavioural Therapy; CBT) in the acute treatment of depression, the prevention of subsequent depressive relapse, and the enhancement of wellbeing.

METHODS

We aim to recruit 80 depressed participants and randomise them 1:1 to receive ADepT (15 weekly acute and 5 booster sessions in following year) or CBT (20 weekly acute sessions). Clinical and health economic assessments will take place at intake and at 6-, 12-, and 18-month follow-up. Reductions in PHQ-9 depression severity and increases in WEMWBS wellbeing at 6-month assessment (when acute treatment should be completed) are the co-primary outcomes. Quantitative and qualitative process evaluation will assess mechanism of action, implementation issues, and contextual moderating factors. To evaluate proof of concept, intake-post effect sizes and the proportion of individuals showing reliable and clinically significant change on outcome measures in each arm at each follow-up will be reported. To evaluate feasibility and acceptability, we will examine recruitment, retention, treatment completion, and data completeness rates and feedback from patients and therapists about their experience of study participation and therapy. Additionally, we will establish the cost of delivery of ADepT.

DISCUSSION

We will proceed to definitive trial if any concerns about the safety, acceptability, feasibility, and proof of concept of ADepT and trial procedures can be rectified, and we recruit, retain, and collect follow-up data on at least 60% of the target sample.

Multidimensional Self-Concept in Elementary Education: Sport Practice and Gender

Background: The purpose of this study was to analyse the relation between the number of hours of organized sports practice and self-concept, considered from a multidimensional approach (physical, emotional, academic, social and family self-concept). The relation between these variables as a function of gender was also investigated. Methods: We used a sample of 840 students from fifth and sixth grade of Elementary Education (494 boys and 346 girls), aged 9 to 12 years, from Spain. To assess the students’ self-concept, we used the AF-5 Self-Concept Form 5 questionnaire. Results: The results show that children who practice organized sport, present a better physical self-concept (0 h a day [h/d]: M = 5.20, SD = 1.82; 1 h/d: M = 5.90, SD = 1.82; 2 h/d: M = 5.99, SD = 1.56; 3 h/d: M = 6.00, SD = 1.42). Boys present a higher emotional self-concept than girls (p < 0.05). Moreover, children’s sports practice is beneficial for the academic and family self-concept but in the case of girls, a high number of hours of daily practice may be decreasing these potential benefits. Conclusions: The findings suggest that organized sports practice could have a positive effect on self-concept. We underline the importance of encourage children to practice sport and paying particular attention to gender differences in the development of the emotional self-concept during elementary education.

Negativity bias and instability in spontaneous and deliberate evaluations of others: The role of borderline personality features

This study tested the hypotheses that borderline personality (BP) features are characterized by a negativity bias and instability in spontaneous and deliberate evaluations of others. Undergraduate women (N = 204) watched two movie clips depicting either positive or negative conjugal interactions. Spontaneous and deliberate evaluations of the male character were assessed after each clip with an Evaluative Priming Task and a self-report measure, respectively. Participants with high BP features showed unstable spontaneous evaluations. Results revealed a non-significant trend toward more negative spontaneous evaluations after the negative clip and less positive and more negative deliberate evaluations after watching the positive clip first relative to participants with low BP features. These results provide preliminary evidence that impression formation in borderline personality may be characterized by negative and unstable evaluations that are shaped at least in part at earlier processing stages.
